Abstract

The invention relates to an antenna device. The antenna device comprises an antenna ground and further comprises a first antenna and a second antenna. A grounding end of the first antenna is connected with the antenna ground. The first antenna is of a transversely arranged F-shaped structure whose opening faces the antenna ground. The first antenna works at two frequency ranges. A grounding end of the second antenna is connected with the antenna ground. The second antenna is of a loop antenna structure. The working frequency range of the second antenna is different from those of the first antenna. The grounding end of the first antenna and the grounding end of the second antenna are connected so as to enable the first antenna and the second antenna to be connected to form an integral structure. A gas with a preset width is arranged between one end, which is not connected with the second antenna, of the first antenna and one end, which is not connected with the first antenna, of the second antenna. The antenna device is capable of realizing multiband work, and the communication requirements of the antenna device are realized. The first antenna and the second antenna in the antenna device form the integral structure, so that the installation and the fixing of the antenna device are convenient. The invention further discloses a mobile terminal.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a mobile terminal and an antenna device thereof. Background technique [0002] Antennas are widely used in various wireless communication equipment terminals, for example, mobile terminals such as mobile phones are provided with antenna devices. In order to meet the miniaturization development requirements of the mobile terminal, the spatial size of the antenna device also needs to be miniaturized. However, with the increase of wireless communication providers, different wireless communication providers often use different signal transmission frequency bands. In order to ensure the normal wireless communication of the mobile terminal under different wireless network environments, the antenna device needs to be able to realize multi-band operation. The antenna device often implements multiple frequency bands by adding multiple independently set parasitic r...
